where did you get those test results?
tirerack has
1. Dunlop Direzza Z1 Star Spec (see above for GRM rankings)
2. Bridgestone RE-01R
3. Yokohama ADVAN Neova AD07
4. Kumho Ecsta XS
5. BFGoodrich g-Force T/A KD
just throwing that out there
GRM= Grassroots Motorsports The Hardcore Sports Car Magazine
....and Tirerack ranks their tires by customer surveys, not their actual test results, so it's not accurate, for instance the BFG g-force Super Sport A/S has faster lap times than the RS2 but you would never know by their rankings and the Michelin PE2 is classified as a UHP tire bust is faster in the wet than the best extreme and max performance summer tires. The new P Zero isn't even ranked. Tirerack is only useful if you look at their "actual test results" and compare them.
Just spent a couple hours ranking the wet skidpad and braking results(so driver error is minimal) for Extreme, Max, UHP, and UHP A/S to get the actual standings and found some surprising stand outs for those of you that like to drive fast in the rain:
1. Pirelli P Zero (new model)
2. Goodyear Eagle F1 Asymetric
3. Dunlop Z1
4. Firestone Firehawk Wide Oval wow!
5. BFG KDW2
6. Goodyear GSD3
7. BFG SS A/S
8. Bridgestone RE760
9. Yokohama S4 (consumerreports.org tested the Falken 912 and Nitto Neogen better)
10. Micheline Exalto PE2
11. BFG KDW
12. Fuzion ZRi
13. Yokohama S Drive
14. Goodyear Eagle GT A/S
Combined dry skidpad and braking rankings:
1. Dunlop Z1
2. P Zero (new)
3. AD07
4. KDW2
5. KD
6. RE760
7. Kumho MX
8. RE-01R
9. Goodyear F1 Asym'
10. Avon M500
11. Contisport3
12. Michelin PE2
13. HTRZ III
14. S Drive
15. ES100
16. Goodyear F1 A/S (best winter A/S tested)
17. BFG SS A/S
18. RE960
19. Yoko S4
20. Hankook RS2
out of 41 tires! Call it a labor donation lol. As you can see, some tires are not in both lists, but the ones that are you can combine the ranking and the lower the number the better. My pick for bang for the buck in 235/40R18 XL is the Bridgestone RE760, looks good too.
For those of you that want to see the actual numbers start here
